Compare and Contrast Plant and Animal Cells

In 2013, average Americans used about 80 times the energy that was provided by their diets, which has been called having 80 energy slaves, but that understates the reality. A barrel of oil provides about one year of the calories needed to fuel a human body, but if that oil were used to power machines, it would perform more than ten man-years of work, often doing work that humans could not perform in any case, such as propelling an automobile. Each American really has several hundred energy slaves working for him/her, which is why the average American lives a richer lifestyle than Earth’s richest human of two centuries ago. In 2013, the energy in the oil wrested from Earth’s crust contained enough energy to power several hundred energy slaves. Add in the other energy resources, and industrialized humanity rode on the backs of about one energy slaves. In today's industrialized nations, humans perform a tiny fraction of one percent of the actual work done; energy-powered machines perform more than 99.9% of it. In contrast, the reproduction of intelligence is in its infancy. In 2012, humanity's 500 most powerful supercomputers achieved the combined computing power of three human brains. The day that each human has even one "mind slave" is a distant future event.

Some things to pass through and not others. The semi-permeable cell membrane will allow water to enter or leave the cell through osmosis. Plant cells can absorb water through osmosis but will not break because of the cell wall. Animal cells do not have a cell wall. What this means to animals is that they must excrete any excess water that the cells cannot hold.

Problem: How are plant and animal cells similar and different

Oxford University Press, December 2017Over the past few decades, curcumin, a common food additive, has been identified as a potential anti-inflmmatory and anti-cancer compound. Curcumin is a phenolic compound extracted from the Curcuma longa plant, and was traditionally used as a spice for improving flavor and color into dishes of various Asian countries. Curcumin’s health benefits are not a new or surprising finding — the brightly colored compound has been used in Ayurvedic medicine for centuries for its potent anti-inflammatory and anti-tumor properties — but the fundamental mechanisms underlying its anti-cancer potential still remain an active area of interrogation. Intriguingly, curcumin has been shown to sensitize multiple cancers to chemotherapy drugs, and several recent studies have reported that curcumin is able to specifically target cancer stem cells. . As suggested by other groups, not only did we demonstrate that curcumin was able to enhance the sensitivity of gemcitabine in these resistant cells, we found that curcumin was also able to inhibit the growth of cancer stem cells. In our study, we also discovered that curcumin was regulating a class of non-coding RNA called “long non-coding RNAs” (lncRNAs). LncRNA is a relatively newly discovered type of non-coding RNA — RNA which does not make protein — found to be dysregulated in most cancers. We discovered that curcumin inhibits the expression of one of the most well-known lncRNA-based oncogenes, a gene that drives cancer, called PVT1. This lncRNA drives tumor progression through the regulation of another well-recognized oncogene, called EZH2. EZH2 is one of the oncogenes known to be involved in drug resistance and is identified to be a potential drug-able target. Though the generation of specific EZH2 inhibitors remains challenging, the findings from our study indicate that curcumin could be used to inhibit the expression of EZH2, as well as the non-coding RNA that regulates EZH2. Considering that curcumin is a commonly available health supplement, it presents itself as a non-toxic compound and incredibly cost-effective compound for the potential treatment of cancer patients.

Rather, we can hypothesize that each organism is composed of different cells and that the cell size varies with the particular kind and function of each cell (for instance, see the discrepancy in the size of different human cells).
